To al( whom it may concern.'

llc it known that we, EARL Biiinnvos and llenar (l. Brumes, citizens of'the 'United Stat-esT and residents of lviilwaulrec, ll'visconsin, haveinvented certain new and useful llmprovenients in Piano-Flanges7 ofwhich the following is a specification containin'- a full, clear, andexact description, reference being had to the accompanying drawings7forming a part hereof.

Our invention relates to piano flanges7 our object being to simplify andcheapen the construction of' 'the different forms of flanges used in apiano action, and to provide a construction which is easily assembled ortaken apart and which readily maintains the pivot pins of the variousparts, such as the hammer butt, damper, fly or jack and whip9 in properposition and alineinent.

To the above purposes, our invention consists in certain novel featuresof construction and arrangement of parte which will be hereinafter morefully set forth, pointed out in the claims, and illustrated in theacconr panying drawings, in which:

Figure l is an elevation, partly in section, of a piano action andshowing` a continuous .metal rail and our improved flanges in position.for use; Fie'. is an elevation, partly in f section, of a portion of ametal rail and showing a series of hammer butt flanges of our improvedconstruction in position thereon Fig. 3 is a perspective view of ahammer butt flange constructed in accordance with our invention; Fig. ilis a perspective view` of a modified form of a hammer butt flange; andEig. 5 is a perspective view of afly flange constructed in accordancewith our invention.

Referring by numerals to the accompanying drawings: l designates a metalangle rail which carries the hammer butts and dampers of a piano action,and formed in the angle rail are grooves 2, in which are seated metalstrips 3, utilized for the pur pose of obtaining correct alinement ofthe hammer butt and damper flanges.

designates the hammer butt, 5 the fly or jack, 6 the whip and 7 thedamper7 all of which parts are of the usual construction.

The hammer butt flange comprises a rectangular metal plate 8, throughthe lower portion of which is formed an aperture 9, which receives thescrew 10, utilized for rigidly fixing said flange upon the rail l,

and formed in the rear face of this flange below the aperture 9 is ahorizontallyv disposed groove ll, which receives the strip or bead 3located in the face of the vertical portion of the rail l. Formed in therear face of this flange 8 adjacent the upper end thereof is ahorizontally disposed vl-shaped groove l2, in 'which is seated a pivotpin 13 carried by the lower end of' the hammer liutt el, and to rigidlymaintain this pivot pin in position a screw l-f is seated in a screwthreaded aperture l5 formed through the flange 8 immediately adjacentthe groove 12, the rear side of the head of which screw hears directlyupon the central portion of the pivot pin. f

In the modified form of the flange seen in Fig. d, the if-shaped groove1Q. for receiving the pivot pin is formed in the end of the flange, andthe screw-threaded aperture l5 which receives the screw 11i is formed inthe end of the flange immediately adjacent said groove.

The damper flange 1G is similar in construction to the construction ofthe form of flange seen in Fig. il, with the exception that said damperflange is provided with a notch or recess 17, in which is located thelower end of the damper spring.

The fly or jack flange comprises a rectangular head or block 18, withwhich is formed integral a threaded shank 19, which is screw seated inan aperture formed in the whip 6, and formed in one of the side faces ofthe block or head 18 is a transversely disposed V-shaped groove 20,which receives the pivot pin carried by the hifureated lower end of thefly 5, and formed through the block `or head 18 immediately adjacent thegroove Q0 is a screw threaded aperture :21,1 which receives a. screw 22,the rear face of the head of which bears against the central portion ofthe pivotpin seated in the groove 20.

Gui' improved flanges are applicable for either wood or metal rails, canbe easily and quickly attached to the rails or to the various parts of apiano action7 and said flanges can be very cheaply manufactured for thereason that but little stock is required and very little millingorspecial toolv work necessary in the production of said anges.

The essential feature of our improved flange is the V-shaped grooveadapted to receive the pivot pin and a screw detachably o r o o seatedin the flange, the head of which screw bears against the pivot pin andrigidly clamps the same to the flange.

`We claim:

l. A metal ilange for piano actions, coinprising a metallic member inwhich is formed an angular groove adapted to receive a pivot pin, saidmetallic member having a screw-threaded opening formed therein adjacentsaid groove and a screw positioned in said screw-threaded opening, aportion of the head of which projects beyond a wall of said groove andis adapted to engage the pivot pin seated in the groove.

2. ln a piano action, the combination with a metal rail provided with abead, of a metal flange provided with an angular groove adapted toreceive a pivot pin and a groove adapted to receive said bead, a screwcarried by the flange, a portion of the head of which projects beyondthe wall of one of said grooves and is adapted to engage the said pivotpin, and a screw carried by said flange for fastening the flange to themetal rail.

3. A metal flange ior piano actions, comprising a metallic member inwhich is formed an angular pivot pin seat, a screw-threaded openingformed in said metallic member adjacent said pin seat, a screw seated insaid opening, a portion of the head of which projects beyond a wall ofsaid pin seat groove, said metallic member being provided with a grooveparallel to the pivot pin seat and an opening between said lastmentioned groove and the pin seat, and a screw located in said openingfor attaching said flange to the piano rail.

l. A metal flange for piano actions, comprising a metallic member inwhich is formed a V-shaped groove adapted to receive a pivot pin, saidmetallic member having a screwtlireaded opening formed therein adjacentsaid groove, and a screw positioned in said screw-threaded opening, aportion of the head ot which projects bevond a wall of said groove andis adapted to engage the pivot pin seated in said groove.

In testimony whereof, we have signed our names to this specification, inpresence oi two subscribing witnesses.
